' IMPROVBD WRENCH FOR CARRIAGE-WHEELS.

lOv ALL` WHOM `IT MAY OONOERN:

Be it known that I, LEVI B. FISH, of Lockport, in the county of Niagara, and State of New York, have invented a certainnew and useful Improvement in Wrenches for Carriage-Wheels; and I do hereby declare that the following is alfull and' exact description thereof, refereneebeing had to the accompanying drawings, in whichli Figure 1 is a longitudinal section, showing my wrench as applied to the hub of a wheel.

Figure 2 is a front view of a wheel-hub, showing the holes in the rim necessary for the useoi my wrench.

Figure 3 is a perspective view of the wrench.

Like letters of reference designate corresponding parte' in all the iigures.

My invention consists of a wrench combining two protruding prongs or-forks for setting into corresponding holes in the wheel-hub, andra socket for receiving the nut on the end ofthe axle, the whole being formed so as to firmly hold-the 4head of the nut-and turn it by the action of the wheel, as hereinafter described. i

In the drawings, A represents the wrench. B is a socket cast in the face of the wrench, m'ade'to conform to the shape of nuts commonly used to hold axles in the hubs of wheels. C C are twostraight forks ofthe wrench, which are cast on the face, and opposite to each other, and `protruding as shown. D is the ordinary nut screwed on the axle, the head resting in the socket B ofthe wrench. E vis the'iron axle, with its end screwed into the nut D. F F are two holes inthe wheel-hub, into whichxthe forks C C set. H is the hub, and Gr the outer rim or band of the hub. I l

The operation of my invention is as follows: When it is desired to remove the wheel, an ordinaryjaok is I placed under the axle, and the wheel raised above the ground. The wrench is then taken by the handle, and the prongs or forks C C inserted in the holes F F insidethe rim oi' the hub.. This action causes the head of the'nut D to set completely in the socket B,`which now closely encompasses it. The operator, with his hand, now turns the wheel on its axis, which furnishes all the power required, and the nut at once begins to unscrew with the wheel. When the nut`is entirely unscrewed, thcrwrench,.still holding-the'nut, is withdrawn from the hub, and the wheel is thus easily taken -from the axle, It is put on byv simply reversing the action.

The object of my invention is to furnish a cheap and compact hand-wrench, simple inconstruction, and which can be used quickly and handily in taking oil whcelsot' all siz'es.' A

To remove the nut, all the power required is'that used in turning the wheel.

My invention does away with the disadvantages of the old styles of wrench, which require considerable strength to apply, especially where a nutis very tightly screwed on to the axle, or has become set by thc'f hardening of the wheel-grease, as-is often the case, and invariably greasingoncs hand and clothes. My device removes a nut without the hands coming in conta'ct with it, and an axle can be greased, andthe wheel and nut put in place, w'ithout soiling the hands in the least,

It is not as unsightly in shape and appearance, no.:` need it be so heavy, as the old st'ylc of wrench. It needs no adjusting, being cast in one piece; and all lthat is absolutely necessary to its use, is'to have the holes bored into the wheel-hub, which, being inside therim, do not show except on close examination, and are not in the least unsightly or objectionable.

- No wheel, however nicely varnished, or hub that is finely plated, need ever be injured or deiaced by thc use'of my wrench. v l

I am aware of a wrench patented-.by Ohareles N. Morgan, August 7, 1866, No. 56,980, which is for removing nuts automatically from carriageaxles; but his device is essentially different from mine, being quite com# plicated, havingjaws,'screws, socket-plate, Ste., and being also very expensive.` His, composed of many parts, is objectionable, asbeing liable to get out of order, or the parts to get lost; also, especially the jaws or clamps, setting' tightly on the painted or plated rim ,of the hub, are apt to scratch or deface it, if it is necessary to apply great power, as where the nut gets set or stuck in'place. As .no part of my wrench touches the rim, no diii= culty of this kind can be experienced.

As the size of nuts used for buggies nndwagons varies, by making thee or four sizes of my wrench, I can obviate all dieulty in lthat respect.'

What Iclaim as my invention, and desire to secure by Letters Patent, as a. new article of manufacture, is A hand-wrench combining the forks C C and socket`B in a single device, when employed in connection with the hub-holes F F, the whole arranged and oper'ating in the manner und for the purpose herein described.

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
